9/11 truth is a form of activism and disagreement with the official story coming from the 9/11 commission created in the aftermath of the September 11th terrorist attacks. Many believed with experts testifying that the Twin Towers of the World Trade Center can handle planes hitting the buildings, some demolition experts believed that the building was imploded by explosives, that the World Trade Center changed their insurance to cover planes hitting the buildings, and many other factors that the activists believe that the terrorist attacks were actually an inside job by the Government to bring the people into fear to take their rights away. Many organizations and activists have become 9/11 truthers including Alex Jones of Infowars, 9/11 truth movement, and 9/11 truth movement activists that goto New York City to give people different viewpoints about the terrorist attacks. They are usually mocked by some people for their viewpoints.

9/11 truth always uses non-mainstream forms of media to promote their views and facts that led to their viewpoints such as forums and websites, documentaries, social networking sites, and other mediums to promote that the 9/11 commission needs to be investigated for the possible coverup of what really happened during the September 11th terrorist attacks.
